risk ? what risk ?
- kernel update = formaility, if it doesnt work i can boot recue system
- openssh update = necessary, quite a lot of security updates out
- chrooted user directory = worst it could do is lock a few people out of the ftp for a while
- services update = good idea in general
- php safe mode and hardening = GOOD idea in general, i just hadnt gotten around to it yet
- sudo and sudoers = once its setup, its VERY VERY usefull.
imo thos is low risk high gain server surgery, and you dont have to do a thing ...
